SOUND Ver.5, a traffic simulator for wide area road networks.
Simulation On Urban road Network with Dynamic route choice
SOUND (Simulation On Urban road Network with Dynamic route choice) is a mesoscopic traffic simulation model which was originally developed in the Institute of Industrial Science, the University of Tokyo, and was commercialized by i‐Transport Lab. Co., Ltd., a venture company in Tokyo.
It is applicable to the road network of the 1 - 100 km scale to evaluate various traffic control & management scheme. The latest version of SOUND is merged with AVENUE, a microscopic traffic simulation, and shares its user‐friendly graphic user interface.

Special Features of SOUND
- applicable to a large urban scale road network.
- a mesoscopic traffic simulation model which deals discrete vehicles with 1 second update interval according to the fundamental diagram of traffic flow.
- dynamic route choice capability taking account traffic congestion, travel time, toll charge, etc.
- incident modeling for lane closures and road closures.
- traffic signal control capability for an intersection with auxiliary lanes and regulations on turning direction.
- customization on traffic information provision and route guidance service.
- interactive data editing through GUI.
- layered management for flexible data build.
- 2D/3D animation of vehicle motions.
- recording animation movie.
- import digital road map and GIS polygons for zones.
- project administration mode to put related cases in order.
- batch calculation mode to run multiple cases at once.
